Double Row Angular Contact Ball Bearings

3200 5200 Double Row Angular Contact

The design of these bearings incorporates two (2) rows of balls into a single inner and outer ring and accommodates a thrust load from either direction. Obviously, they are much wider than a single row bearing and perform as if two bearings had been installed. NTN’s double row angular contact ball bearings are made using diverging angles of contact. The illustration shows how the opposing 30° contact angles do not converge (come together) within the bearing’s inner ring; therefore they are described as "diverging" or "divergent." Double row angular contact bearings also come in either a maximum capacity version (with filling slots) or standard (non-filling slot) types.

NTN’s designation for double row maximum capacity (filling slot) bearings is a 3 in the first position of a four (4) digit base bearing number and a 5 in the first position of a four (4) digit base bearing number to indicate a double row, non-filling slot type ball bearing.
